1995 Ls400 Differential Noise With Video


Recommended Posts

Background I have a vibration from 65mph and up

its worse when accelerating or decelerating

both wheels have a very small amount of play when pushed at 12 o clock

there is no howling as is described with other diff problems

you can see the sound coincides with the metal moving in and out.

I took a leisurely ride last night with the wife in the Lexus (she thought we were just going for ice cream instead of a test run for noises...LOL) there is definitely no noise similar to this while moving. At slow speeds i can hear a faint high pitched squeak which I think is the wheel bearings.

The vibration at 70mph is still there, otherwise it is very quiet.

I'm thinking that when the wheels are off the ground the weight of them pulls the axles away from the differential and that pulling is allowing the bearing to move in a way to create this noise.
